mile maker has sevral on the market that is ran from the power stearing pump it will pull the full load at idle and you can get a remote to go with them i have used one many times on fire runs and you cant beat them with a stick.
what good is a elc.wench if you are stuck you get unstuck and now have a dead batt. This is a very powerfull set up and it only takes about half of the space to mount it. the install kit has all the fittings and hoses to make a very prof. install.
just my two cents worth.
